- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Some necesary fixups to cope with new location and FreeBSD CVS keyword.

Add the GEOM regression test framework.

This is a set of userland shims in which GEOM can be run through simple
tests.

The simulation of kernel synchronization primitives is very primitive
and consequently some times tests will fail because of races.

Data/ contains a number of files in XML format which describe the
key sectors for a number of disk images

This is a very handy tool for people developing GEOM methods. The
"simdisk" method can be told to read from a "real disk" and afterwards
dump the accessed sectors in XML format for further use.

I hope future method writes will see the benefit of this test
collection and add to it when they write methods for GEOM.

You will need ports/textproc/expat for the XML parser.
